Hello, this is my first post in this forum, but sometimes I visit it to get some news. Now we have an issue and I need your advice. Few months ago we were awarded with a project that use PTH components. We solder these components on Wave soldering

There are several things that can be done. Shortening the lead length should eliminate bridging between lead. We had done a project several years ago where the customer had shortened the leads to almost flush to the board, preventing any chance of

If the package is robust enough to handle surface mount followed by a pass through the wave soldering process, we have had excellent results populating the fine pitch parts with the P&P machine, reflow, then mask the solder joints prior to wave solde

Most companies are double sided paste and reflow, then selective soldering the thru-hole. This will give you the best results and with much more consistency than with Wave Soldering.

I think you have your pitch wrong but anyway, I have never had success with wave soldering anything less than 50 mil pitch. On a QFP I have had good luck on three sides of 25 mil but never all four sides and without defects. Mask 'em off and hand s

Is it possible to wave .02mm fine pitch? I get excessive bridging. Any ideas welcome. Thanks Brian

Are you talking 0.02" (1.225mm) if so then no it's not a great idea. if you must wave it can you go to a PLCC and through hole socket it on the other side of the board?

Thanks a lot,, so assuming we are using standard parts, with nothing out of the ordinary we could safely assume that a machine capable of 20 mil would be more than able to meet our needs down the road. | We are changing from through-hole to SMT, won
